Изобретение относитс к машиностроению , в частности к ггриводам с ходовым винтом, используемым дл преобразовани вращательногс) движени в пос- тупательное.The invention relates to mechanical engineering, in particular to lead screw drives used to convert rotary motion into contraction.
Цель изобретени - повышение КПД за счет снижени трени ,The purpose of the invention is to increase efficiency by reducing friction,
На фиг. 1 изображен привод, общий вид; на фиг. 2 - то же, продольный разрез; на фиг. 3 - корпус с выемкой дл наружного кольца подшипника,продольный разрез; на фиг. 4 - кольцевой выступ и часть ходового винта.FIG. 1 shows the drive, general view; in fig. 2 - the same, longitudinal section; in fig. 3 - housing with a recess for the outer ring of the bearing, longitudinal section; in fig. 4 - annular protrusion and part of the spindle screw.
Привод содержит корпус 1, в кото- ром размещены ходовой винт 2 и по крайней мере один эксцентрично установленный подшипник 3, ось 4 которого лежит в плоскости, перпендикул рной оси 5 винта 2, и не Пересе- каегс с последнзй. Т шутреннее кольцо 6 подшипника 3 имеет кольцевой выступ 7, предпазначЕ нный дл взаимодействи с резьбовой канавкой 8 винта 2. Привод также ссщержит корпус 9 с выемкой 10 дл нар окного кольца 11 подшипника 3, котора в поперечном сечении представл ет собой полуокружность . Между внутренним 6 и наружным 11 кольцами подшипншса 3 размещены te ла 12 качени , выполненные в виде шариков . В корпусе 1 имеютс радиальные резьбовые отверсти 13, в которых размещены устан 5вочные винты 1А, св зывающие корпус 9 подшип-ника 3 с корпуThe drive includes a housing 1 in which the lead screw 2 and at least one eccentrically mounted bearing 3 are placed, whose axis 4 lies in a plane perpendicular to the axis 5 of the screw 2, and does not cross with the latter. The teething ring 6 of the bearing 3 has an annular protrusion 7 assigned to interact with the threaded groove 8 of the screw 2. The drive also brakes the housing 9 with a notch 10 for the outer ring 11 of the bearing 3, which in cross section is a semi-circle. Between the inner 6 and outer 11 bearing rings 3 are placed a rolling body 12, made in the form of balls. In case 1 there are radial threaded holes 13, in which are mounted the installation screws 5A 1A, which connect the case 9 of bearing 3 to the housing
сом 1 привода. Привод также снабжен радиальными подшипниками 15, предназначенными дл установки ходового винта 2 в корпусе 1. Радиус 16 кривизны кольцевого выступа 7 составл ет 0,7- 0,9 радиуса 17 резьбовой канавки 8 винта 2. В этих пределах радиус 16 выбираетс с таким расчетом, что в точке 18 при-пожени сил между ходовым винтом 2 и кольцевыми выступами 7 касательна 19 к выступу 7 проходила примерно под углом З к продо- льной оси 5 ходового винта 2.Som 1 drive. The drive is also provided with radial bearings 15 for mounting the lead screw 2 in the housing 1. The radius 16 of the curvature of the collar 7 is 0.7-0.9 of the radius 17 of the screw groove 8 of the screw 2. Within these limits, the radius 16 is selected so that that at point 18, between the lead screw 2 and the ring protrusions 7, the tangent 19 to the ledge 7 passed approximately at an angle Z to the long axis 5 of the lead screw 2.
Привод работает следующим образомThe drive works as follows

При вращении ходового винта 2 корпус 1 привода получает поступательное перемещение через промежуточные элементы - подшипники 3, св занные с корпусом посредством установочных винтов 14. При этом снижение трени достигаетс за счет выполнени профил выемки в виде полуокружности в поперечном сечении. Той же цели служат и размещенные в радиальных резьбовых отверсти х установочные винты, которые позвол ют регулировать эксцентричность подшипника, чем регулируетс взаимодействие между ходовым винтом и подшипником.When the lead screw 2 rotates, the drive body 1 receives translational movement through the intermediate elements — bearings 3, associated with the housing by means of set screws 14. In this case, friction is reduced by making the recess profile in the form of a semicircle in cross section. The same purpose is served by the set screws placed in the radial threaded holes, which allow the bearing to adjust the eccentricity, which regulates the interaction between the lead screw and the bearing.
